The delete-r simply sends a FF code (every 10 minutes) to clear out codes caused by the HiFlow converters. It is merely a convenience to keep the interior lamp from turning on with no effects on performance.

Tuning is not required - but significant gains have been shown afterwards. Tuning is also an alternate way to deal with the CEL issue.
